Brings in the external FEM gain preferences (fem_txgain, PR #3137 plus the
companion-side port), the AGC reset rxgain fix, the LR2021 preamble/IRQ
timeout logic, and assorted variant fixes (T096, T-Echo Card TCXO, promicro
pinmap, minewsemi, R1 Neo).
Conflict resolutions:
- SH1106Display: both sides fixed T-Beam Supreme startup independently. Kept
our _initialized guard and DISPLAY_ADDRESS_ALT override, took upstream's
SA0-pair fallback and its unconditional display.begin() so the frame buffer
is allocated even when no panel answers.
- MyMesh/SensorMesh/CommonCLI: took upstream's fem_txgain default and wiring,
kept our comments and the observer-side prefs layout.
Also fixes CustomLLCC68Wrapper, which upstream missed when sx126xResetAGC
gained its rx_boost_gain parameter. No variant builds that wrapper today, so
neither tree failed to compile.
PA PL1 re-targets the PA's DC-DC supply rail rather than selecting a
logic-level gain, and the serial CLI is serviced on every main-loop pass
regardless of whether a transmit is in flight. A `set radio.fem.txgain`
write could therefore move the rail mid-transmit, while the SX1262 was
still driving the PA at full input power.
Record the requested level in setPAGainEnable() and drive the pin from
setTxModeEnable(), which runs from onBeforeTransmit() ahead of
startTransmit(). The level only matters while transmitting, so deferring
costs nothing.
Document that the pref is saved immediately but applied at the next
transmit, so `get radio.fem.txgain` can lead the hardware until then.
Neighbors publication was gated on BOARD_HAS_PSRAM. Removing that gate alone
was not enough: the feature built but was inert without PSRAM, because three
allocation sites asked for MALLOC_CAP_SPIRAM (which returns null with no
PSRAM), the bridge's persistent buffer was allocated inside a BOARD_HAS_PSRAM
block, and neighborDiscoverReady() rejected every pass at runtime on
psramFound(). The entry table also did not fit: finishNeighborDiscover put
pubkey_hex[50][65] plus entries[50] on the stack, a 4752-byte frame against
the mesh loop task's 8 KB.
- Gate on MAX_NEIGHBOURS plus PSRAM or an explicit per-variant
MQTT_NEIGHBORS_WITHOUT_PSRAM opt-in.
- Move the entry table and its hex strings into one heap block sized to the
pass; the frame drops from 4752 to 304 bytes.
- Prefer PSRAM and fall back to internal DRAM in the mesh-side allocations
and the ArduinoJson pool; hoist the bridge's persistent buffer out of the
BOARD_HAS_PSRAM block (psram_malloc already falls back).
- Keep the runtime psramFound() check only where the buffers are sized for
PSRAM, so a board whose PSRAM failed to init still refuses.
- Size for internal DRAM without PSRAM: 4 KB text buffer and 20 entries per
publish, keeping the pool to a single block and the peak near 13 KB rather
than ~35 KB. Oversized tables truncate and report total_neighbors as before.
Enabled on the ESP32-S3 observer envs (Heltec V3/WSL3, RAK3112, Heltec
Tracker v1.1/v2). Left off for the classic ESP32 T-LoRa V2.1-1.6, which is
already limited to one active TLS slot.
Costs ~7.4 KB static DRAM on repeaters and ~9.6 KB on room servers. The
prefs layout is unchanged, so this is neutral for existing devices.
Absorbs 106 upstream commits. Seven files conflicted; the substantive one
was upstream's new JSON ConfigSerializer (PR #2982), which replaces the
binary /com_prefs layout with /prefs.json and makes NodePrefs a
ConfigSerializer subclass.
Prefs migration
- Adopt upstream's ConfigSerializer. writeCommonPrefsImage() and its
documented offsets (0-294) are deleted, along with the now-unreachable
saveCommonPrefsImageAtomically()/CommonPrefsFileStore atomic rename path.
- Load order is /prefs.json, then /com_prefs, then /node_prefs. Upstream
dropped the /node_prefs fallback; it is restored here so devices that
never advanced past that filename keep their config.
- Legacy files are never removed, so migration cannot destroy its own
source and a deferred or failed save simply retries next boot.
- /com_prefs is treated as a format migration only, not an "upgrade", so
it does not trip the bridge.source tx->rx flip on existing nodes.
- The MQTTPrefsAtomicStore legacy gate is retained: the observer tail
recovered from an old-format file still commits to /mqtt_prefs before
/prefs.json is written.
- MQTTPrefs and /mqtt_prefs are untouched; savePrefs keeps its save_mqtt
parameter and now returns upstream's bool.
Fixes to upstream code
- RadioPrefs::structure() bound both "rxgain" and "fem_rxgain" to
rx_boosted_gain, so radio_fem_rxgain was never persisted. Bound to the
correct field.
- discovery_mod_timestamp was dropped from structure(); it gates
'since'-filtered DISCOVER replies and is set on every config change, so
losing it would silently stop discovery responses after a reboot. Added
as "disc_mod".
Merge artifacts repaired
- Restored bblanchon/ArduinoJson to the native test env; a clean but wrong
auto-merge at the lib_deps block boundary dropped it and broke all 19
host test suites.
- Migrated the fork's WebConfig UITask screens off the removed
DisplayDriver::Color enum to upstream's UIColor element types.
- Removed duplicate getCADEnabled() definitions in companion MyMesh.cpp
and simple_sensor SensorMesh.cpp that both sides had added.
- Dropped memset(&_prefs, 0, ...) in the four example meshes; NodePrefs now
has a vtable. guard gains an initializer that memset used to provide.
Other resolutions
- simple_room_server keeps both the fork's discover.* commands and
upstream's new room.post.
- docs/payloads.md taken from upstream, undoing content earlier merges had
reverted (Control data section, split login tables).
Verified: 273/273 host tests pass across native and native_kiss_modem;
Heltec v3 repeater, repeater_observer_mqtt, room_server_observer_mqtt,
sensor, and companion_radio_ble all build clean.
Enhance the documentation for the `start ota` command to clarify its
behavior when connected to a Wi-Fi network versus when using the
`start ota ap` option. This provides users with better guidance on
how to initiate OTA updates under different network conditions.
First upstream merge since the 2026-06-06 base (191 upstream commits). 14 files
conflicted; resolutions below.
Fleet-critical check (Constraint 1): upstream reordered NodePrefs members
(rx_boosted_gain / path_hash_mode moved to the struct tail) but did NOT change
/com_prefs. Persistence is written field-by-field at explicit offsets, so member
order is in-memory only. Verified the fork's writeCommonPrefsImage() is
byte-identical to upstream's inline writer at every offset (79 pad, 121, 122,
290-294). No migration needed.
Resolutions:
- CommonCLI.h: kept the fork's NodePrefs (superset) and adopted upstream's
setRxBoostedGain(bool)->bool signature change, which CommonCLI.cpp now uses to
report unsupported. Corrected a stale comment claiming rx_boosted_gain lives at
offset 79 (it is a pad; the field is at 290).
- CommonCLI.cpp: kept the fork's legacy /com_prefs migration and the extracted
writeCommonPrefsImage() call.
- UITask.cpp: three-way merge - upstream's drawTextCentered + powering-off
screen, plus the fork's WITH_WEBCONFIG portal/reboot screens.
- ESP32Board.cpp, MeshCore.h, platformio.ini: kept both sides (fork OTA additions
alongside upstream powerOff/enterDeepSleep and Packet.cpp).
- MicroNMEALocationProvider.h: took upstream's claim/release and added the
_claims member they depend on.
- MyMesh.cpp/.h (repeater + room server): kept the fork's superset defaults.
- Removed duplicate declarations auto-merge produced: RadioLibWrapper::_cad_enabled
and MyMesh::getCADEnabled().
Verification: native suite 15/15 (incl. upstream's new test_mesh_tables), both
MQTT smoke builds green, ArduinoJson pin check passes. Hardware validation next.
Implemented new commands for configuring and diagnosing NTP server
settings in the MQTT bridge. Users can now set a custom NTP server
and probe connectivity to configured servers. This enhancement
improves time synchronization reliability for JWT authentication
and provides better diagnostics for NTP connectivity issues.
Extract the inline cursor-walk in handleRegionCmd into file-local
helpers (skipSpaces, rtrimSpaces, takeToken, splitNameJump,
processRegionDefSegment), grouped immediately above the consumer.
Behavior is identical; addresses PR #2540 review feedback on
readability.
Tighten the region def docs: collapse five Note callouts into three
grouped paragraphs (Behavior / Existing regions / Limits), add a
case-sensitivity caveat plus an error example, note the cursor reset
between split commands, and use generic placeholder names.
Add a new command `region bulk` for defining region hierarchies in a single line. This command allows users to create multiple regions in a single message. Updated the documentation to include usage examples and detailed parameter descriptions.
Updated the MQTT message structure to add a new field for repeat status, allowing the indication of forwarding status as "on" or "off". This change includes modifications to the MQTTMessageBuilder and related documentation to reflect the new parameter. Additionally, updated CLI command documentation to clarify flooding behavior in different firmware versions.
Changed the default setting for TX packets from disabled to 'advert' across multiple files, including documentation and example implementations. This aligns the behavior of the MQTT bridge with the new default preferences, ensuring that only the node's own advert packets are uplinked by default. Updated relevant comments and documentation to reflect these changes.
Introduced a new CLI command to view and set the radio watchdog interval, allowing users to configure the watchdog timeout in minutes (0 to disable, 1-120 for active). Updated the documentation to reflect this addition and clarified the parameters for the `neighbor.remove` command. Default watchdog interval is set to 5 minutes in the codebase.
